Popup having suboptimal position on websites with specific layouts

[ChaseOxide]

Description
Happens when:

• (horizontal-tb) start of term at the bottom, ends at the top
• (vertical-rl) start of term at the left, ends at the right

It can be reproduced if the website uses column layouts.

My reproduction:

<div id="data" style="height: 600px; column-width: 100px; width: 300px">
</div>
<script>
  data.textContent = Array(100).fill('こんにちは。').join('')
</script>

Tiny screen (500x624)

#2135 makes some internal improvements to make this edge case handled a bit better. There is still potentially some room for improvement (which is more complex), but this is how it should look now (depending on popup size settings):
